There are several ways that dentin can become exposed leading to tooth sensitivity.
Here are a few common causes of sensitive teeth resulting from dentin exposure:
- Gum recession due to gum disease.
- Overaggressive brushing or brushing with a hard bristled toothbrush.
- Too many acidic foods and beverages.
- Teeth grinding.
- Tooth decay or physical injury to the tooth.
- Recent dental procedure.
Always see your dental professional for tooth pain that is severe or consistent and lasts for more than a day or two, but if you have the sharp, shooting pains commonly felt with tooth sensitivity, use products that are designed to block the tubules and relieve the pain including toothpaste for sensitive teeth and gums.
